i imagine yuriy would be friendly. he hasn't dated really for a while now, so it is likely it wasn't noticed that he had anyone over--he wasn't bringing them to the garden, anyway. he had his daughter living with him up until almost two years ago, and focused on that realm of life and all. he definitely could have noticed adrian, though. and his daughter set him up a tinder this winter, so it is possible they could come across each other, yeah, and then it be shown they are both into both genders and just see how it goes.
